VULCANIZING DEVICE FOR RUBBER TIRES.

mess.

y-To all whom 'it may concern:

' Be it known that we, WILLIAM C. RIS- 'BRIDGER and MILTON W. RISBRIDGER, citizens of the United States, residing at Cleveland,

in the county of Cuyahoga and State of Ohio, have invented certain new and ,use-

Improvements in Vulcanizing Devices for Rubber Tires, of which the following is a specification.

f Th's invention relates to a vulcanizing ide vice for rubber'tires, and the invention consists in the construction and combina- -t1on of parts'substantially' as shown and the claims.

In the accompanying drawings, Figure 1 is a side elevation of the tire partially sectioned in its lower portion. Fig. 2 is an elevation of the device shownin connection described and particularly pointed. out in with a table and a tire flattened out thereonin vulcanizing position. Fig. 3 shows a section of a wheel and tire thereon with the device in vulcanizing position thereon reverseto Fig.2. Fig. 4 shows an enlarged 'section of wheel and tire and the vulcanizer suspended thereon with the parts in vertiv .pal' al nement inside view,'.and Fig. 5 is a -}cross section on line w-w, Fig. 4, showing especially the relation of the parts to each other and to the'wheel when in this vulcanizing position.

As thus shown the complete device is comprised in three associated parts specifi- I a hollow shell or member shaped preferably as shown and having an open bottom and depending hooks h ortheir equivalent at its {side-s adapted toserve as a support for the burner of lamp L. In construction and preferably the said lamp, or burner is barrel ehaped with flat ends and has trunnions 2 Specification of Letters Patent.

eccentric'ally disposed in said ends and adapted to be hung upon the said hooks h. By placing said trunnions relatively above the center of said barrel the bar-' rel holds its working position by gravity in any and all the relations of the same to the body B and Whatever the vulcanizing positions, asseen in Figs. 2 t0 4 inelusive. For convenience one of said trunnions has a key shaped wing 3 adapted to be grasped by thumb and finger to handle the lamp. At its bottom said lamp or barrel-- has a'plugged opening 4: through which it is filled and at its top it has a' circular opening and projection 5 adapted to receive a Wick for ignition to maintain the desired flame. In this instance we also provide a flat spring 6 depending from the. rear wall of body B and bearing frictionally against said barrel and serving to prevent easy rocking of said barrel from its proper position beneath thebody B, as hereinafter fully set forth.

At its top the body B has a suitable opening 7 and opposite circular openings in its front and rear wall adapted to receive the 3 tubular hub 10 of the vulcanizing member V. Said hub is cylindrical in shape and has a hole and plug 11 in its end through which water is introduced for the vulcanizer, the said hub being cast integral with the body of the vulcanizer V and open thereto interiorly. The vulcani'zer itself is ahollow member adapted to receive steam at a vul canizingteniperature, and for this purpose the hub 10 is essentially the boiler for said member. I

In construction the whole part V necessarily includes the hub or boiler 10 but is peculiar and original in this that said hub is at one end and entirely at the side of the body of the vulcanizer, so that when the hub is inserted in the bodyv member B and locked. to work therein the body of the vulcanizer is wholly at one side of and apart from body B and in a plane of its own. This is material on several accounts, as is obvious, and chiefly for its advantageous workin disposition to the said body B. Thus, take Fig. 2 for example, where the tire T-is flattened out on a table or stand S and the flat side of the vulcanizer is applied to the tire while the body B and its lamp in upright position swing at the side of the table. Or,

refer to Fig. 3, where the T is on the wheel -in distended form and the vulcanizer is thrown with-its concave side lengthwise upon the tire in line with the periphery of the wheel. Here again body B is in swinging or suspended relation bodily at one side h of the vulcanizer and lamp L hangs normal.

Like relations and advantages are. shown in the other twoworking positions, Figs.

' has what are believed to bewholly original from the single and only working of its being pivoted in said body as shown and exceptional possibilities as differentiated position of body B and lamp Lfand all by reason and adapted to swing about the same in almost a complete circle and stop at any point in the circle for work. The said vulcanizer V is provided with open slotted projections let oppositely at its edges adapted to receive a supporting chain C, not new and a handle H is pivotally supported on one edge of said vulcanizer and adapted to throw the same to one'position or another in use.

The hub or boiler 10 of the vulcanizer has a small lug aon its edge and end adapted to be rotated around and pass through notches b in the shell when the said hub is to be withdrawn or inserted. Otherwise the said lug is sufficient to confine the hub in working position. This or any other means .may be employed to hold said parts separably together. By locating said hub or tubular'stem 10 as shown and described it really comes at the lower end of the vulcanizer and hence it will follow that when said hub is charged with water the water will generally remain therein where it' is" designed to be heated, though of course some will flow into the shank or arm at which connects said hub with the body of the vulcanizer.

Rubber tubes generally as well as pneuf matic tires may be mended bv this device although it is especially intended for automobile tires.

The draft from the heater or lamp L is up throughbody B and the products of combustion pass about the sides of hub or stem 10 and heat the same before issuing through hole 7 at the top.

The lamp or heater L is rotatably supported on its bearings and engaged and held by spring ti for the express purpose of holding said lamp in working position with the flame wholly inside. or wholly outs1de,.as

seen in full and dotted lines respectively in Fig. 1, or the fianie may be divided, say half inside and half out according to the demands of the vulcanizer. lVhen the requisite steam heat has been obtained in the vulcanizer the lamp will maintain the same by supporting member provided with circular openings through the side walls thereof and openings in bottom and top and a vulcanizer havin a hollow body and a tubular stem atits end and side rotatably mounted in said side walls open to said body.

3. A device for vulcanizing tubular tires 'and like articles comprising a hollow body having openings bottonrand top,'in combi nation with a vulcanizer constructed to be steam heated internally and having a hollow hub at its edge adapted to receive water and rotatably mounted in openingsin the' side walls of said. body, and a burner beneath thereby fill said vulcanizer withsteam.

'said body adapted to heat said hub andv 4. The device substantially as described I comprising t-wo working members, a hollow body with a draft upward through the same and a vulcanizer having a water containing stem projecting at substantially right angles from-its edge and rotatably mounted in said hollow body, and a heating device suspended beneath said body.'

5. A vulcanizing device having av hollow body with a draft through the same bottom to top and having depending hooks, a heater suspended on sald hooks and a vulcanizer supported wholly at one side of said body and pivotally mounted through the sides thereof, said vulcanizer having a hollow portion in said pivot open to the interior thereof and adapted to receive water to be heated.

6. A vulcanizing device having a hollow body open through its center for draft and a heater in its bottom, in combination with a vulcanizer having alateral hub pivotally mounted in the top of said body and open to said hub, said hub provided with a plugged opening to introduce water, and means 0 separably confine said parts together working relation.

7. A vulcanizing device having a body with an internal heating chamber and a vulcanizing member having awater receiving extension at its side rotatably mounted in said chamber and exposed. to the heat therein.

.8. A vulcanizing device comprising ahollow vulcanizing body and a. heating body pivotaliy united, said vulcanizing body having a laterally projecting tubular stem pivoted in said heating body and open to the interior thereof, and said vulcanizing body adapted to swing in the arc of a circle to either side of said heating body.

9. A vulcanizing device comprising a hol- 10W Vuloanizing member having fiat and concave sides respectively and provided with a tubular fluid heating stein project- 5 In test-iinon Y whereof we aflix our si 0 natures in presence of two Witnesses.
